Siphoning the fuel
First, place the chainsaw on a level surface to ensure stability and safety. Remove the spark plug boot to prevent any accidental startups while you work. Now, you'll need to access the fuel tank. To do this, locate the gas cap and lift the locking lever to the vertical position. With the lever in this position, turn the cap counterclockwise and remove it from the chainsaw. If the cap is connected to a plastic strap anchored to the tank, let it hang freely.
With the gas cap removed, you can now access the fuel tank. Place a gas can next to the fuel tank of the chainsaw. This will be used to collect the fuel that you'll siphon out. Insert a hand siphon into the fuel tank and the opposite end into the gas can. Start siphoning the fuel out of the chainsaw and into the gas can. Continue until you've removed all the fuel from the chainsaw's tank.
Once the fuel is completely siphoned out, you can proceed to the next step of replacing the fuel filter. Remember to wear protective gear, such as gloves and eye protection, during this process. Additionally, ensure you have a suitable tool to remove the fuel line from the fuel tank, as this is necessary for accessing and replacing the fuel filter.
Please note that it's essential to dispose of the siphoned fuel properly and in accordance with local regulations. Also, always refer to the owner's manual of your specific Stihl chainsaw model for additional instructions or variations in the process.
